adapted to feed blanksof sheet'mstsi 'mennen ,t-ire- 'vceiving machine as for instance a can body machine or' thelike. l

-Heretofore considerable diiiicultyhasbeen found in to the various lrapidly operating automatic machines One serious objection to that requentlytwo or V.more

ously instead of but one as required thus wasting `stock and causing frequent'delays and breakages ofmachinery; It is als true that with the suction'feedmech-m.

' Visms heretofore used it has been difficult, if not impossible-to feed lthe blanks continuously to the receiving manature of thesefeed mechanisms a considerable interval necessarily occiirs between delivering th'e successive blanks and even with feed mechanisins of this class it is not-,uncommon to have two or moreblanksfd atthe Sametime. Furthermore withl the devices heretofore used complicated mechanisms have been required likely to frequently get out of order.

. `The object of 'this `invention to provide aconstruction adapted to permit the blanks to' .be -fed either at intervals apart or in a-centinuous line ,as preferred, and so constructed as to 'absolutely preclude the`possibility of more than one `blank com ing from the device at one time thus remedying the objections above stated.

f It is also an object of the invention to provide an extremely strong,V cheap, simpleanddurable construction adapted for either slow or rapid operation and not likely scribed and more appended claims.

friction wheels Ev'the rotation of said friction wheels in th'e direction indicatedby the arrow in Fig. 1 draws said innermost blank d downwardly along the inclined table bending Uie same'suiciently to spring the same aw-ay from the adjacent blanks separating the same therefrom Aand,eventually dropping the blank` upon the table in position to be, fed into the machine. As each blank is drawn downwardly and away from mutilated portionoi the periphery' is priming the samer but :the remainingportion of the peripher'yfshouldbe sov vertically and in vdetails of construction `'may the remaining blanks in the stack gravity tendsto slide l the stack into position for the next blank to be supported by the rollers b5 in postition to friction wheels. If the periphery be a true circle the next blank is engaged the moment the preceding blank is released therefrom and for this reason the device can be timed to deliver a continuous succession of blanks to the receiving table with no appreciable interval between successive blanks. Obviouslyi it is desired to provide an interval between the blanks as is necessary invthe'case of some receiving machines, the eed mechanism may be run slower or as shown in the drawings the periphery of the friction wheels -E may be cut away for a part oi the circumerence so that for a part ot a revolution of said friction wheels the same are out of-engagement with the blanks. 'In the event oi the periphery oi said wheels being mutilated it is obvious that no ymovement of the blanks `can occur while Ithe oi a length to insure the blank being carried-tree of the Afriction wheels.' Obviously the interval between suc l-cessive blanks is determined by 'the -sp'eed lof rotation of said friction wheels and the portion -of their pe- Aripheries removed. y j i v The friction wheels may be oi any suitable l'material and may be driven by any suitable means and many be varied without depart- 'ing from the principles of this invention. .t
